LED flickering with a frequency of approx. 10 Hz
1 flash
LED 200 ms on, 1400 ms off
2 flashes
LED 200 ms on, 200 ms off, 200 ms on 1000 ms off
3 flashes
LED 2x (200 ms on, 200 ms off) + 1x (200 ms on, 1000 ms off)
4 flashes
LED 3x (200 ms on, 200 ms off) + 1x (200 ms on, 1000 ms off)
Table 6: Indicator states
Note:
Red and green LEDs are strictly switched in phase opposition according to the CANopen
Specification [3].
For certain indicator states viewing all LEDs together might lead to a misinterpretation
of the indicator states of adjacent LEDs. It is therefore recommended to look at the
indicator state of an LED individually, in covering the adjacent LEDs.
